lMPROVE M ENT IN HAND-STAMPS.

Specification forming part of Letters Patent No. 203,915, dated May 21,1878; application. filed November 20,1877.

To all whom it may concern:

Be it known that I, BENJAMIN B. HILL, of Springfield, in the State ofMassachusetts, have invented a new and useful Improvement inHand-Stamps; and that the following is a full, clear, and exactdescription thereof, reference being had to the accompanying drawings,making a part of this specification, and to the letters of referencemarked thereon.

My invention relates to a hand-stampin which the printing characters aremade upon endless rubber bands passing over a drum above, or a series ofdrums, and over a bar at the lower end of the stamp; and it consists ofa drum, or series of drums, each having a corresponding disk or flangeattached thereto, which flanges are sufficiently larger in diameter thanthe diameter of the drums to project considerably beyond the thicknessof the bands which pass around the drums, so that any one of the drumsmay easily be turned to move the corresponding band without touching anyof the bands themselves.

Figure I is a perspective viewof my invention, showing the drums andflanges arranged in a case or frame; and Fig. II is a transverse sectionof the same, showing the drum and its flange, and also the position ofthe rubber bands. I

In the drawing, A represents a case or frame, made with bearings insideto support the shaft 0, upon which a series of drums, D, are placed,around which pass the rubber bands a, having printing characters made ontheir outside surfaces. Each drum D is provided with a disk or flange,B, considerably larger in diameter than the drum, the periphery of whichdisks may be milled, to be more easily turned when grasped.

The hands a pass around a Zbar, f, at the bottom, each band beingstrained sufficiently taut in passing around a drum and the bar to beheld firmly in, place for making an impression. 7

When an impression has been made, and it is desired to move any one ofthe bandsa for the purpose of bringing other characters into positionbeneath the bar for printing, it is done by taking hold of the disk B,attached to the drum carrying the band it is desired to move, androtating it until the desired character upon the band is brought intoposition.

Any number of these drums may be used in a series, each provided with adisk, B, by

which to move the drum and band, and may be used for dating purposes ornumbering, or both combined.

If a case is used entirely covering the hands a, except at the bottom,openings or slots 0 may be made in opposite sides of the case, throughwhich a portion of the flanges or disks protrude, so that they mayberotated or moved by the fingers applied to them outside the case.

Having thus described my invention, what I claim as new is Thecombination of a series of drums, D, each provided with a disko'rflange, B, the single shaft 0, upon which said drums are arranged torotate, and a series of printingbands passing around and moved by saiddrums, whereby any desired band in the series may be moved by turningthe corresponding flange or disk and its drum, substantially asdescribed.

BENJAMIN B. HILL.
